We don't know.  No-one seems to know.  The ACA _might_ know, but they
don't seem to be telling anyone.  :)

Notionally, a carrier licence is required to provide "carriage services".
As in, links that may carry "third party" traffic.

You don't require a carrier licence to send Internet traffic over phone
lines, because Telstra (for example) is providing the "basic carriage
service" and _they_ have a carrier licence (or did last time I looked).

I'd suggest it is, if no packets from the Internet actually reach the
wireless network clients.  As in, the wireless connected DNS server only
provides Internet name resolution + local [slave] zones to the wireless
clients.

I suspect you can reasonably compress the two nameservers and LAN segment
into the one machine with both wired Internet and wireless connectivity.

I think this is where you might run into trouble, since you're still
operating at network layer 3 and pretty much forwarding Internet IP-level
traffic between wired and wireless networks.

Warning: IANAL!  This is pure speculation on my part.
